My invention relates tolaundry tubs formed of synthetic stone, and hasamong its objects and advantages the provision of an improved metalfacing along the upper edge and partition of the tub.

In the accompanying drawing:

Fig. 1 is a perspective view of a tub embodying the invention;

Fig. 2 is a sectional view along the line 2-2 of Fig. 1;

Fig. 3 is a sectional View along the line 3--3 of Fig. 2;

Fig. 4 is a fragmentary detail view, partly in section, viewed from theposition indicated by lines 4-4 of Fig. 3;

Fig. 5 is a perspective view of the corner connection between two piecesof metal facing; and

Fig. 6 is a plan View of a facing strip before it is formed.

In the embodiment selected to illustrate my invention, the tub I!)comprises end walls 12, side walls I l and I6, and an integral partitionl8. The tub is provided with a metal facing 28 along the upper edges ofthe end and side walls and a metal facing 22 along the upper edge of thepartition I8. I provide one piece of facing for each of the walls, whichpieces are shaped to assemble in interfitting relation to provideeffective metallic covering for the corner portions of the tub, asindicated at 24.

Referring to Fig. 2, the facing 20 comprises a single strip of sheetmetal bent to provide a flat top surface 28 and a wall lining surface 28separated from the surface 26 by the curved corner portion 30. The otheredge of the surface 26 is bent at 32 and again at 34 to offset a portionof the strip with respect to the surface 26, which offset portion isbent to provide a curved part 36 and an inwardly projecting flange 38.Similarly the wall lining 28 is bent at 48 to provide an inwardlyprojecting flange 42. Both flanges 38 and 62 are imbedded in theconcrete comprising the wall 14, the material of which completely fillsthe metallic facing.

The specific configuration of the facing in crosssection provides a tubedge devoid of sharp corners in addition to enhancing the ornamentalappearance of the finished product. At the same time the curved parts 30and 36, together with the offset part between the lines 32 and 34,provide a reinforced facing capable of withstanding rough usage. Becauseof this construction the individual facing pieces will retain theiroriginal straight alignment so that the finished edges of the tub willalways be true in addition to eliminating the difiiculty of accurateplacement within the mold so that straight tub edges may be formed.

I have discovered that a metallic facing having a surface 26 extendingthe full width of the upper edge of the tub tends to buckle after itsassociation with the wall of the tub so that the facing will have a wavyappearance. My reinforced construction, together with the narrow surface26, prevents buckling of the metal.

My corner connection between the individual pieces of the facing 20 isdesigned to provide a blunt or curved corner Ml, thereby eliminating thesharp corner characteristic of commercial tubs.

Referring to Fig. 5, each piece of the metallic facing 20 has an end 16terminating in a straight line at right angles to the longitudinal axisof the piece, and its opposite end bent to provide a lip 48 arranged atright angles to the piece proper.

In Fig. 6 I illustrate the lip 48 as being formed integrally with thefacing proper, which lip is bent generally along the line 58 to providea curved vertical corner 52 and shaped in the area indicated generallyat 54 to provide the curved corner 44. In cutting the blank, asindicated in Fig. 6, the corners 44 and 52 may easily be formed by a dieto provide a gentle curvature of smooth configuration.

The lip 48 is arranged in interfitting relation with the end 46 of itsassociated facing piece. I bend the lip 48 at 56 to provide a flangehaving a curvature conforming to the curved part 38. Before the twoparts are assembled, the flange 42 is bent, as indicated at Fig. 5, toprovide a trough 58 for the reception of a portion of the lip 48. Whilethe lip 48 lies inside the lining surface 28, the remaining portion ofthat piece of facing 20 lies over a portion of the straight end of theother piece, as indicated by the overlapping illustration of Fig. 4.

Referring to Fig. 6, the V-shaped end portion 68 provides an endformation when the blank is bent into the finished article which closelyembraces the curved part 36 and the flange 38. This arrangement providesan effective connection in which the tendency for either part to shiftwith respect to the other by rotary movement about its longitudinal axisis entirely eliminated.

I have also found that the reinforced construction prevents portions ofthe overlapping parts of the interfitting facing pieces from bending 50easily so that very little difficulty is experienced in assembling thepieces Within the form preparatory to pouring the concrete.

In Figs. 3 and 4 I illustrate the shape of the metallic facing 22 forthe partition 18. This piece 55 is bent to provide a fiat surface 62 andtwo curved and flanged edge parts 64 conforming in configuration to thecross-sectional shape of one side of the facing pieces 20.

In Fig. 4 the facing 20 associated with the wall I6 is cut out at 66 toreceive the facing 22. The shape of the cut-out is illustrated in Fig.5. In Fig. 4 I illustrate the ends of the facing 22 as being straightand in right-angular relation with the facing proper with a portion ofthe surface 62 as lying underneath the surface 26 of the associatedfacing 20.

Without further elaboration, the foregoing will so fully explain myinvention that others may, by applying current knowledge, readily adaptthe same for use under various conditions of service.

I claim:

1. In an upright tub Wall having an angle therein, metallic facingsalong the top surface of the wall and having flanges extendingdownwardly over portions of the outer faces of the wall, the ends ofsaid metallic facings having overlapping relation at the angle of thewall, one of said metallic facings being provided with a convex areaextending around the outer sides and top of the wall at said angle, saidflanges including inturned portions anchored in the material of thewall, one of said flanges being bent back upon itself to provide atrough for the reception of the other flange.

2. In an upright tub wall having an angle therein, first and secondmetallic facings extending along the top surface of the wall, each ofsaid facings including flanges extending downwardly over portions of theouter faces of the wall, the first of said metallic facings having astraight end arranged at right angles to the longitudinal axis of itsfacing, the second of said metallic facings having a flange lip forminga part of its outer flange and arranged at right angles to thelongitudinal axis of said second facing and extending under the outerflange of said first facing, the outer flange of said first facing beingbent back upon itself to provide a trough for the reception of said lip,a portion of said lip and its metallic facing being provided with aconvex area extending around the outer sides and top of the wall at saidangle.
